Glasses for colour blindness.

Postby bladepitch » Sat Oct 22 2016, 11:14

Hi all.

Saw this ad while cruising social media and remembering CASA were making waves about colour blindness not so long ago. I know they have backed down about it now but for those that it may affect in future if it ever pops up again, a simple pair of glasses may be the answer.

That is very cool, never knew it was that simple to sort out.

The truth of the matter is that a colour vision deficiency (CVD) is no disability when it comes to flying by day or night.
Colour is simply not that important in aviation.
In fact there are lots of CVD pilots in all levels of aviation in Australia including some airline captains. I believe there are more than 300 CVD commercial pilots in Australia.

The problem has always been that CASA insist they pass at least one of the available tests. Currently Ishihara, Farnsworth or CAD.
For many years (approx 1990 - 2014) CASA allowed a practical test using the tower signal light that uses proper aviation colours that are readily discernible by most people with a CVD. That was at the insistence of an Australian court (Denison case at the AAT). Many pilots got a clean Class 1 medical that way.

Unfortunately, CASA removed this practical test and replaced it with a non-practical test - CAD. CAD is just another lab test that uses colours in the confusion area of CVD people.

So even if some lenses could 'correct' the deficiency and allow you to pass colour vision tests it is of no real advantage in aviation.
CASA wont let you wear these lenses to try pass a test.
For more info google CVDPA.
